Leners Patent No. 100,247, dated M01/rch 1, 1870.

IMPROVEMENT IN STOP-MECHANISM FOR GARIDING'-MIAGHINE.v

The Schedule .referred to in thesev Letters Patent and making partf thesame.

To all whom it may con-cern Be'it known that I, C. W. ANDERSON, ofGrosvenor Dale, in the county of Windham, and State of Connecticut, haveinvented a new and improved Stop- Motion for Carding-Machines; and I dohereby cleclare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the' same, reference being had to the accompanying drawingsforming' part of this specification.

This invention relates to devices employed to throw out of gear thedriving mechanism of the cal-dingengine when the fibre breaks ordoubles, and consists in the combination and arrangement of certaininstrumentalities whereby this object may be more convenientlyeii'ected, and which will be more particularly specified hereinafter.

' In the accompanying drawing- Figure 1 represents a vertical transrelsesection of my invention, the planeof section being indicated by the line:c x, fig. 2. Y

Figure 2 is a front view,.partly in section, of the same.

Figure 3 is a horizontal section of the same, taken on the plane of theline y y,lfig. 1. v

Similar let-ters of reference indicate corresponding parts. y

A, in the drawing, represents the frame of the railway bead.

,B is the shipper-bar.

This bar, when it holds the belt on the tight pulley, is inthe positionshown in figs. 2 and 3, and is retained in such position by alock-lever, C.

y vA spring, D, or itsequivalent, has the tendency, by turning the shaft1, around which it is coiled, to draw the bar B out by means of the beltJ, connect-ed at one end to the bar, and at the other to the shaft I, soas to throw the driving-belt upon the loose pulley.

On the bar B is a spring-catch, a., which serves to engage the lever C.

'lhe lever C is a bell-crank, with a long horizontal and short verticalarm.

The horizontal arm is caught under one arm, b, of an elbow-lever, E,which is pivoted by a vert-ical pin, c, to the frame.

A spring, d, has the tendency to draw the arm b off thelever C.

Through the top plate of the frame A passes a bar, F, which is pivotedto projecting ears, e, as shown, so that it can swing forward andbackward on the same.

The lower end of the bar F passesA through the arm f of the elbow-leverE.

Its upper end carries a trumpet or funnel, G, through which the leece ispassed.

The cotton, as it is passed through the funnel, swings the same forward,throwing thereby the lower end of the barF inward. This will cause thearm b of the lever E to be held over the long a'rm of thel lever C,whereby the short arm of the latter will beheld against the spring-catcha.

The shipper-bar will thus be locked so as to retain the belt ou thetight pulley.' t

As soon, however, as the. fleece is separated, the strain on the funnelG and bar F will cease, and the spring d will be at liberty to draw thearm b of ther lever E on" the long arm of the lever C. v

The power ofthe spring D willthen be exerted to throw the shipper-baroutward, and shift the belt upon the loose pulley, the lever C beingswung out of the way by the power of the spring D.

Thus, as soon as the bers shall be separated, and the eece that vleavesthe carding-machine be torn, will the shipper-bar be 'moved tothrow thebelt upon the loose pulley, and to thereby arrest the motion of themachine.

H isa lever pivoted to the frame A in front of the lever F. Its front orouter end is designed to rest upon the upper vertically-movable rollerh', while its rear end, which has a cam formation, ts against a pin, i,`that projects from the lever F.

When the roller h. is raised by crowding or doubling -of' materialbetween it and the roller h, the lever H 1. The combination ofthe'mechanism'for operat- Y ing the belt-shipper from the funnel whenthe sliver breaks, consisting of the vert-ical swinging-bar F, levers CE and springs D d, when constructed and ar-. ranged with respect to eachother,v in the manner described. v

2. The combination with the pivoted lever F and the rollers h h' of theloosely-pivoted roller H, constructed and arranged as described, withone end resting over the journal of the movable roller h, and the otherprovided with a graduated cam bearing against a pin projecting from thelever F, by which the beltshipping mechanism is operated when the slivervdou-y bles or crowds between the rollers, all as set forth.

3. The combination with a pivoted bar, E, for operating belt-shippingmechanism, of a funnel G affixed to the -top thereof, and avibrating-lever H, resting with its cam end against the pin t', andoperated by the elevation of the looselyjournaled roll h', all arrangedas speciied, and for the double purpose of throwing the driving-beltfrom thefast pulley whenever the sliver breaks or doublesbetween therolls.
